FIELD

The present application is directed to a cable connector and to anelectrical box assembly having a cable connector for securing a cable tothe box. The application is particularly directed to an electrical boxhaving a cable connector where the connector provides a sliding andsnap-in connection for the electrical cable and particularly for metalclad and armor cables.

BACKGROUND

Electrical cables are commonly supplied to an electrical junction boxfor connecting the cable to electrical fixtures or other electricalcables. The cables generally pass through an opening in the wall of theelectrical box and are secured in place by a suitable claim.Conventional cable clamps generally clamp the cable between the clampingplate and a side wall or bottom wall of the electrical box. This type ofclamping arrangement generally relies on the smooth surface of the wallof the electrical box that does not adequately grip the cable.

Cable clamps are produced which are able to accommodate metal armorcable and plastic sheath cables. These devices include a stop member forthe metal sheath to prevent the metal sheath from extending into theelectrical box. Various clamping devices are known for clamping theelectrical cable. Many of these cable clamps are mounted to the cableand then inserted into the opening in the electrical box so that atleast a portion of the clamp projects outwardly from the outer surfaceof the electrical box.

One example of an electrical cable clamp is disclosed in U.S. Pat. No.4,316,999 to Nattel which discloses an electrical wiring box and cableclamp where the cable clamp is attached to the wall of the electricalbox. The cable clamp is a flexible member that overlies the opening inthe electrical box bottom edge of the leg portions including upwardlyturned flanges. The bottom wall of the electrical box includes ridges orscore lines for engaging the nonmetallic cable.

U.S. Pat. No. 4,922,057 to Ross discloses an electrical box having aflexible flat retaining member attached to the inner face of the sidewall of the electrical box. As shown in FIG. 2, the flat retainingmember flexes to grip the surface of the cable passing through theopening in the electrical box.

U.S. Pat. No. 4,724,282 to Trader discloses a nonmetallic electrical boxhaving a flexible metal cable retaining member attached to the innerface of the electrical box. The retaining member flexes when the cableis passed through the opening to grip the cable.

U.S. Pat. No. 4,277,641 to Bauer et al. discloses a nonmetallicelectrical box having a cable clamp member that is inserted into thecavity of the electrical box. The cable clamp member includes an outerframe and a flexible flap. The flexible flaps bend upon insertion of theelectrical cable through the opening in the frame to grip the cable.

U.S. Patent Publication No. 2012/0024596 to DiLillo et al. discloses aplastic cable clamp adapted for mounting in one of the openings in theelectrical box. The cable clamp includes one or more flexible memberscapable of clamping the nonmetallic cable. In one embodiment, the cableclamp includes flexible legs that can bend inwardly upon insertion ofthe cable to grip the outer surface of the cable.

While the prior cable clamps and connectors are generally suitable forthe intended use, there is a continuing need in the industry forimproved cable clamps and connectors.

DETAILED DESCRIPTION

The application is directed to a cable connector and to an electricalbox assembly that includes an electrical box and a cable connector fornon-metallic sheathed cables, metal clad and armor cables. The cableconnector of the invention avoids the use of separate connectors thatare often required for coupling metal clad, armor and non-metalliccables to an electrical box. Electrical codes require the use of someform of connector for securing the cables to the electrical box.

In one embodiment, a pre-assembled electrical box assembly has a cableconnector as a fixed part on the electrical box to avoid the need forseparate connectors or handling of separate connectors. The cableconnector is attached to the electrical box in a pre-assembled form foruse by an electrician without the need to install the cable connectorson the job site. In one embodiment, the cable connector is fixed to theelectrical box by welding, screws, coupling tabs, or other means forattaching the cable connector to the box during the manufacture of theelectrical box. In one embodiment, the cable connector is permanentlyfixed to the electrical box at the time of manufacture.

In one embodiment, shown in FIGS. 1-9, the electrical box 10 includes acable connector 12 that is secured to a surface of the electrical box 10to form the electrical box assembly. The electrical box 10 is typicallymade from steel by deep drawing, by cutting and bending from a blank orby joining cut pieces together to form the electrical box into thefinished shape as known in the art. The cable connector 12 issufficiently resilient to allow the cable to pass through the cablepassage and grip the outer surface of the cable.

The electrical box 10 is constructed in a manner similar to aconventional electrical box by having an open front 14, a rear wall 16,and one or more side walls extending from the rear wall 16 to define theopen front 14. In the embodiment shown, the electrical box 10 has afirst side wall 18, and a second side wall 20 opposite the first sidewall 18 and connecting walls 22 extending between the first side wall 18and the second side wall 20. In the embodiment shown, the electrical box12 has a substantially square shape although the electrical box can haveany suitable dimension and shape. In other embodiments, the electricalbox can be rectangular, hexagonal, round or other suitable shape.

In the embodiment shown, the first side wall 18 includes at least oneand preferably two cable openings 24 extending through the wall forfeeding the cable 26 to the interior cavity 28 of the box 10. In theembodiment shown, the two cable openings 24 are positioned next to oradjacent one side of the box. The second side wall 20 is also shownhaving two cable openings 30 positioned on an opposite side of the boxso that the cable openings and the respective cables are staggered withrespect to each other so as not to interfere with each other when fedinto the electrical box. The electrical box can have any number of cableopenings as known in the art.

The electrical box 10 and cable connector 12 are preferably preassembledas a single, one-piece, integral unit or assembly for installation bythe electrician without the need for attaching separate connectors tothe cable and/or the electrical box during installation. The inventionis particularly suitable for use with non-metallic sheathed cables,metal clad cables, or armor cables 26 having internal electricallyconducting wires 32. The metal clad cables as shown have a spiral woundcorrugated metal sheathing 33 as known in the art.

The cable connector 12 can be attached permanently to the electrical box10 at the time of manufacture in manner to prevent separation of thecable connector 12 from the box 10 during normal use. In the embodimentsshown in the drawings, the cable connector 12 is attached by welding,riveting or other fastening means to the rear wall 16 of the electricalbox 10 to align the cable connector 12 with the respective cableopenings 24 and 30. In other embodiments, the cable connector 12 can beattached to one or more of the side walls so that the cable connectorsare aligned with the cable opening 30 in the electrical box 10. Althoughthe cable connector 12 is preferably fixed to the electrical box, thecable connector can be attached to the electrical box by a snapconnection such as by a prong that snaps into an aperture in a wall ofthe electrical box.

The cable openings 24 are generally provided in the side walls althoughcable openings can also or alternatively be provided in the rear wall.In one embodiment of the invention, the cable connector 12 is attachedto a suitable surface that is substantially perpendicular to the wall orsurface with the cable opening.

Referring to FIGS. 1 and 2, the cable connector 12 is attached to therear wall of the electrical box by welding. In further embodiments, thecable connector can be attached to the side wall or other surface sothat the cable connector is permanently fixed to the electrical box in aposition to be aligned with the cable access opening 30. Preferably thecable connector 12 is mounted entirely within the electrical box so thatno portion of the connector extends through the cable openings.

Referring to FIGS. 2-9 the cable connector 12 is preferably formed as aone piece, integral member formed of steel or other metal. The cableconnector 12 is preferably formed from a blank metal sheet that is cutand folded into the final shape as shown. The cable connector 12 isformed by a body 34 having a cable passage 36 with a first end 38 and anopposite second end 40. A front wall 42 is provided at the second end 40of the body. The first end 38 of the body 34 is positioned at the sidewall of the electrical box and aligned with the cable opening 24. Thesecond end 40 of the body is spaced from the first end 38 and the sidewall 18 of the electrical box 10.

The body 34 of the cable connector 12 in the embodiment shown in FIGS.1-9 has a first side wall 44 and an opposite second side wall 46. Thefirst side wall 44 and the second side wall 46 are connected together bya top wall 48 extending between the side walls. In the embodiment shown,the front wall 42 is integrally formed with the top wall 48 and extendsdownwardly substantially perpendicular to the top wall 48. The frontwall 42 has an opening 50 for receiving the electrical wires 32 andfeeding the wires to the internal cavity of the electrical box 10. Theopening 50 is formed with a rounded edge 52 to form a smooth collar toprevent damaging the wires passing through the opening 50.

In the embodiment shown, the opening 50 forms apertures that can have acircular shape or an oval shape that are dimensioned to accommodateelectrical cables. The openings 50 have a dimension to allow theelectrical wires to pass through the opening and a dimension to preventstandard metal armor cable from passing through. In this manner, thefront wall 42 functions as a stop for the armor sheath as shown in FIGS.1 and 2.

In the embodiment shown, the side walls 44 and 46 are inclined withrespect to each other and slightly converge toward the front wall 42. Inother embodiments, the side walls 44 and 46 can be substantiallyparallel to each other. The side walls 44 and 46, the top wall 48 andthe front wall 42 define the longitudinal cable passage 36 that extendsthrough the cable connector 12. The front wall 42 and the opening 50define the second end 40 and outlet end of the cable connector 12. Theopposite end defines the first end 38 of the body and an open inlet endfor the cable 36 passing through the opening in the electrical box.

In the embodiment of FIGS. 1-9, the cable connector 12 has an openbottom 54. The cable connector 12 is attached to the wall of theelectrical box to enclose the cable passage 36 by the side walls 44 and46 and the top wall 48 of the cable connector 12 and the correspondingwall of the electrical box 12.

In the embodiment shown, the rear wall 16 of the electrical box mateswith the open bottom 54 of the cable connector 12. The bottom edge ofthe first side wall 44 includes a mounting flange 56 extendingsubstantially perpendicular to the respective side wall portion. Thebottom edge of the second side wall 46 includes a mounting flange 58extending substantially perpendicular to the respective side wallportion. The mounting flanges 56 and 58 are attached to the rear wall 16of the electrical box to permanently fix the cable connector 12 to theelectrical box. In the embodiment shown, the mounting flanges 56 and 58have detents 56 for use in welding the mounting flanges to the rear wall16. In other embodiments, the mounting flanges can be fixed to the rearwall 16 by rivets or other fasteners. In a further embodiment, themounting flanges can be formed substantially parallel to the plane ofthe respective side wall and inserted through slots formed in the rearwall. The mounting flanges can then be bent and optionally welded toretain the tabs within the slots.

The open first end 38 of the body 34 of the electrical connector 12 hasa dimension to receive the cable 26. As shown in FIG. 2, the first sidewall 44 has a first edge 60 at the first end 38 with a cable retainer62. A first end 64 of the cable retainer 62 coupled to the edge 60 ofthe side wall 44 and a second free end 66. The cable retainer 62 in theembodiment shown is in the form of a leg with the first end 64integrally formed with the first side wall 44 forming a U-shapedconnecting portion 68. The U-shaped connecting portion 68 forms a springmember to spring bias the retainer 62 toward the cable passage and toallow the retainer to bend and flex by insertion of the cable and toprovide sufficient spring biasing force to grip the cable. The retainer62 is bent inwardly toward the cable passage 36 and has a first legsection 70 extending toward the front wall 42 and a second leg section72 bent inwardly towards the cable passage 36. The second leg section 72has a terminal end forming the second free end 66 of the retainer 62 andis formed at an inclined angle with respect to the longitudinaldimension of the cable passage 36 and the plane of the first leg section70. In the embodiment shown, the second free end 66 has a substantiallystraight edge that is angled with respect to the front wall 42.Alternatively, the free end 66 can have a concave shape corresponding tothe shape of the outer surface and dimension of the cable 26. The freeend 66 is formed at an angle corresponding substantially to the angle ofthe corrugations of the armor clad cable so that the terminal end isable to grip the recess between the corrugations as shown in FIG. 2.

The second side wall 46 also has a first edge with a cable retainer 74integrally formed with the side wall. The cable retainer 74 has a firstend 76 coupled to the first edge of the side wall 46 and a second freeend 78. The retainer 74 also has a first leg section 80 coupled to theside wall 46 by a U-shaped connecting portion 82 and extends toward thefront wall 42 at an inclined angle. The U-shaped connecting portion 82define a spring member to spring bias the first leg section 80 towardthe center of the connector and toward the first cable retainer 62 andenable the legs to bend and flex with respect to the side wall. A secondleg section 84 extends inwardly from the first leg section 80 at aninclined angle with respect to the first leg section 80 towards thecable passage 36. The free end 78 of the retainer 74 is formed at aninclined angle opposite the inclined angle of the first leg section ofthe first retainer 62 to grip an opposite side of the armor cladding ofthe cable as shown in FIG. 2. The cable retainers 62 and 74 are orientedso that the free ends converge toward the axis of the cable passage togrip opposite sides of the cable.

As shown in FIGS. 2 and 9, the first retainer 62 has a longitudinallength slightly longer than the length of the second retainer 74 toeffectively grip the spiraling corrugations of the electrical cable asshown in FIG. 2. As shown, the retainers 62 and 74 extend away from thecable opening in the electrical box into the cable passage 36 of thebody 34 and are angled to allow the cable to be inserted through theopening in the electrical box and resist removal of the cable from theelectrical box. The free ends 66 and 78 are angled with respect to theaxis of the cable passage 36 so that the top corners 86 of the free endsproject toward the front wall 42 as shown in FIG. 8 and converge towardeach other relative to the bottom corner 88 as shown in FIG. 6. Theangled free ends of the cable retainers form a V-shaped recess to engagean upper side surface of the armor cable so that the cable is capturedbetween the rear wall 16 of the electrical box 10 and the edges definingthe free ends of the cable retainers.

The cable connector 12 is preferably formed from steel or other metalhaving sufficient strength to effectively grip the cable while allowingthe retainers sufficient resilience to allow the cables to be insertedand removed as necessary. The cable retainers 62 and 74 are formed fromresilient spring steel and have sufficient resilience to deflectoutwardly towards the respective side wall portion by insertion of theelectrical cable while being spring biased toward each other foreffectively gripping the outer surface of the cable.

In use, the cable connector 12 is attached to the electrical box asshown in FIG. 1. The cable connector 12 is aligned with the opening inthe wall of the electrical box so that the cable 26 can be insertedthrough the opening in the electrical box and passed through the cablepassage 36 of the cable connector 12 to the position shown in FIG. 1 andFIG. 2. The opening in the front wall 42 has a dimension to allow thewires 32 to pass through and prevent the armor cladding of the cablefrom passing through the opening. The armor cladding of the cable asshown in FIG. 2 abuts the inner surface of the front wall 42. To removethe cable from the cable connector, a tool can be inserted into thecable connector 12 to pry the retainers 62 and 74 outwardly to releasethe tension on the armor cladding and enable the cable to be pulled fromthe connector.

Another embodiment of the invention is shown in FIGS. 10-19. In thisembodiment, the electrical box assembly 90 includes the electrical box10 and a cable connector 92. The electrical box is substantially thesame as in the previous embodiment so that similar components areidentified by the same reference number. The cable connector 92 has abody formed by the cable retainer 94 at a first end and a front wall 96at a second end spaced from the first end. In the embodiment shown, twocable retainers 94 are joined together as a single unit to grip twoseparate cables passing through adjacent cable openings in theelectrical box. In one embodiment, the cable retainers 94 arepermanently fixed to the side wall.

The cable retainer 94 in the embodiment shown is a flat metal springlike member that is attached to the side wall 18 of the electrical boxby rivets 98 or other fasteners passing through apertures 97 to overlieat least a portion of the cable opening 24. The cable retainer issufficiently flexible to flex so that the bottom edge bends away fromthe side wall and upward from the rear wall of the electrical box whenthe cable is passed through the cable opening 24 so that the cableretainers able to grip the outer surface of the electrical cable.

The cable retainer 94 in the embodiment shown in FIGS. 16-19 is formedfrom a flat sheet of metal that is folded over to form two substantiallyflexible flat legs 100 and 102 for each cable retainer. The legs 100 and102 are substantially flat, planar members and form a flap-like memberoverlying the cable openings. In the embodiment shown, two legs 100 andtwo legs 102 are joined along the top edge and separated by a gap orslot 127 so that each of the legs 100 and each of the legs 102 can bendindependently of each other for gripping separate cables passing throughthe two adjacent cable openings in the electrical box as shown. The legs100 and 102 can have a generally square or rectangular shape andpreferably have width greater than a width of the respective cableopening to extend across the width of the cable openings as shown.

The first leg 100 has a bottom edge 104 with a profiled or scallopedshape for gripping the outer surface of the electrical cable. The bottomedge 104 in the embodiment shown in FIGS. 16-19 has a recess 106 form bytwo converging edges 108 that converge to a slot 110. The convergingedges 108 form the recess 106 with a substantially V-shape complementingthe outer dimension of the electrical cable. The slot 110 divides thefirst leg to form a first tab 112 and a second tab 114 on opposite sidesof the slot 110. Each of the tabs 112 and 114 is able to flexindependently to grip the outer surface of the spiral corrugatedelectrical cable 26 as shown in FIG. 11. The bottom edge 104 is spacedfrom the rear wall of the electrical box a distance less than thediameter of the cable 26 as shown in FIG. 11 so that the cable isgripped with sufficient force to retain the cable in the electrical box.

The second leg 102 has a substantially similar shape to the first leg100 with a length less than the length of the first leg as shown inFIGS. 18 and 19 to extend into the cable openings so that the ends ofthe legs 100 and 102 are spaced apart from each other. The differentlengths of the legs enable the retainer to grip different size cables.The first leg 100 has a length so that the bottom edge 104 is able togrip a smaller cable such as for example a 0.37-0.5 inch diameter cable.The second leg 102 to has a length so the bottom edge 116 is able togrip a larger cable, such as a 0.6-0.6 inch diameter cable. The bottomedges of the legs are spaced from the rear wall a distance less than thediameter of the cable being gripped to provide sufficient force tospring bias the legs against the outer surface of the cables.

The second leg 102 has a bottom edge 116 with a recess 118 formed byinclined edges 119 that converge to form the substantially V-shapedrecess. A slot 120 extends between the inclined edges 108 to define afirst tab 122 and a second tab 124. As shown in FIG. 17, the first leg100 and the second leg 102 are joined together at a top edge 126.
